Who is Brihaspati Bhagwan | Dev Guru Brihaspati?

Brihaspati appears in the Rigveda as a sage born from the first great light, the one who drove away darkness, is bright and pure, and carries a special bow whose string is of cosmic order (basis of dharma). His knowledge and character is revered, and he is considered Guru (teacher) by all the Devas. In the Vedic literature and other ancient texts, sage Brihaspati is also called by other names such as, Surguru, Vachaspati, Jeeva, Bramanaspati, Purohita, Angirasa (son of Angiras) and Vyasa; he is sometimes identified with god Agni (fire). His wife is Tara (or goddess who personifies the stars in the sky). In the Mahabharata, the son of Brihaspati named Bharadvaja is the counsellor of the Pandavas. The reverence for sage Brihaspati endured through the medieval period, and one of the many Dharmasastras was named after him. While the manuscripts 
of Brihaspati Smriti (Bṛhaspatismṛti) have not survived into the modern era, its verses were cited in other Indian texts. Scholars have made an effort to extract these cited verses, thus creating a modern reconstruction of Bṛhaspatismriti. Secondary literature has been the source for reconstructing the Brhaspati sutras partially. Brihaspati became the root of the word 'Brihaspativara' or Thursday in the Hindu calendar. Brihaspati Age from 35 to 42 years, development of consciousness by Jupiter.
